BASEBALL-SHOE PLATE.

Application led November 5,1921. Serial No. 513,088.

To all whom it may concern:

Be it known lthat I, GEORGE DE GROOT, a citizen of the United States, residing at Morristown, in the county of Morris and State of New Jersey, have invented new and useful Improvements in Baseball-Shoe Plates, of which the following is a specification.

'Ihis invention relates to a baseball shoe plate and the object is to provide an aluminum or other metallic plate to be secured to the sole and provided with non-skid devices of a particular type, which will be effective in service and will Obviat-e the possibility of one player injuring the other by accidental contact.

A further obj ect is to provide a plate with a series of engaging devices which will not permit of the accumulation of foreign material, but will remain clean and provide a firm foothold.

A further object is to provide a plate of light'material which may be used by golf players and others requiring an attachment of this kind which will permit of easy walking or running and yet be serviceable for the purpose intended.

A still further object is to provide for connection with a triangular member or plate, an inner portion having engaging devices thereon, this inner portion being ada-pted to be secured by countersunk screws passing through Openings in t-he outer triangular member.

IVith the foregoing and othe-r objects in view, the invention consists in the novel form or construction of the plate including the enga-ging devices thereon, or formed on an inner element, in the manner indicated.

In the drawings, Figure 1 is a bottom plan view, showing the device attached to the sole o-f a shoe; Figure 2 is a fragmentary view, in longitudinal section; Figures 3 and et are bottom plan views illustrating a modification in which the device is formed in two parts, one of which is undercut along the inner edge portion, and the other of which has beveled or chamfered edges.

The element 10 is preferably triangular in configuration, being provided however with rounded corners 11, 12 and 13. The surface le is plain and the edge portion is provided with openings 15 in which the screws 16 may be countersunk.

The inner portion 18 is provided with a central triangular opening 19, and with transverse engaging devices, each including one vertical wall, and one inclined wall. The formation of these engaging devices is import-ant, and it will be noted that the inclined wall of each element is toward the narrow portion of the attachmentf-that is toward the toe portion, thereby enabling the wearer to secure a firm foothold, and at the same time the accumulation of dirt or other material will be prevented.

The inner portion carrying the engaging devices may be formed integrally with the outer port-ion 14., or may be formed vseparately, as shown, and in the latter event this inner portion will be retained by the heads of the screws by means of which the attachment is secured to the shoe. The edge portion 2l of the outer section or triangular frame 22 may also be undercut as shown by dotted lines in Figure 3, and inner plate 23 having engaging devices 23 thereon is shown as being provided with a beveled or chamfered edge 24. j

In Figure l the heel plate with engaging devices 25.

What is claimed is 1. A device of the class described comprising a plate to be secured to the sole of a shoe, and transverse engaging devices carried by the plate and formed to permit of positive engagement with the surface of the ground, in one direction, and to permit of free movement over the surface in the Opposite direction, an Outer plate inclosing the plate first named, and headed devices having shanls in approximate alinement wit-h the meeting edges of the plates, the heads Overlapping both plates.

2. A device of the class described comprising an apertured element of triangular form and provided with a triangular cen- 25 is provided tral opening, a. second triangular element positioned within that first named and having an area corresponding with the Opening therein, said second element being provided with engaging devices on the surface thereof, said elements being reversely beveled at their adjacent edge portions, one of the elements being notched along its beveled portion, and securing means passingV through the apertured element and engaging the notched portions of the other element.

In testimony whereof I affix my signature.

GEORGE F. DE GROOT.
